Actually, I was pretty sure there weren’t really anchovies in the dressing since we were not in a particularly upscale restaurant (Friendly’s, if you must know). However, we could have been at the Ritz eating a salad dressed in 100% anchovies and we’d be having the exact same conversation.

I was in a restaurant and witnessed a customer asking the waiter to take his Caesar salad away, because it tasted "fishy." The waiter removed it to the kitchen, where the chef gave it the taste test. It passed. It was returned to the diner... Who said "Take it away. And be sure to remove it from my bill."
That didn't happen.

Dads are too cute. I have similar conversations with my dad over the telephone (he lives in California and I live in France). Our conversations consist of my either yelling into the phone or repeating myself at least 3 times or he'll think I said "cancer" when I really said, "Kansas". :)
